Seriously though look thru the bumper at the drivers fog and you can it has methanol or not, that will let you know it's at least a stage 2.......if it has the oem fuel rail it's a stage 2.75 or under.....other than that you would have to climb under the car and what size snail it has . There are other differences between the kits but those can be an upgrade on stages lower.

and i know 2 other hpf cars from different car clubs are coming i just want to know the difference from stage 2 to 2.5 and 4... i know the difference on the s/c cars because i have one of those lollllll
but thanks alot now i won't look to stupid to the owners i will at lease know what im looking for and where to look....
